This is a very well made quality leather jacket that would sell for much more at a name brand store. This jacket is ostensibly a leather Navy Pea Coat. Although the sizing data used by the manufacturer is questionable, that fact alone does not warrant, in my opinion, a reduction from a five star rating. To assist future customers in selecting the correct size I provide the following information: I am 5' 8" tall, weigh 170 lbs, with a 42" chest and 33" waist, and I purchased a large jacket. The large jacket fits just right. I can also wear my favorite Irish sweater under the jacket. It is snug fit with the sweater, but it is still comfortable. By comparison, in the Army I wore medium-regular uniform, and field Jacket. So, my recommendation is, if you are 43" or 44" in the chest, and over 34" in the waist, you most likely would want the x-large. Also, if you wore a large uniform in the military, you want to purchase the x-large jacket. I have been wearing this jacket now for a week and I have received five compliments on how good the jacket looks. Needless to say, I am very pleased with this jacket.
